Single Acting Hydraulic Cylinder Manufacturer

There are many types of cylinders that are used in hydraulic systems and single acting cylinder is the simplest form of cylinder in terms of design and functioning. In a single-acting cylinder fluid within the cylinder acts on one side of the piston. When fluid within the cylinder pushes piston from one side it extends the shaft attached to cylinder. The electrically powered pump that is attached to the cylinder forces fluid through hoses to enter the cylinder. This mechanism within single acting cylinder extends the rod or shaft for completing the job, but for retraction of the piston to its original position, it requires an external force to be applied. In most cases, it is the gravitational force that retracts the piston to the reset position. While doing so the hydraulic fluid is pushed back to the reservoir. Some single acting cylinders also are fitted with springs to complete the retraction process.

There are mainly two types of single acting cylinders – push-type cylinders and another is pull-type cylinder. In push type cylinders air is forced into the cylinder to push the piston out of the cylinder and in the case of pull-type cylinders air is used to pull a piston inside the cylinder. Single acting cylinders are especially beneficial if you use cylinder for your jobs that require linear motion in most cases, like clamping, puncing and positioning. This type of cylinder is also good for jobs that require repeatative functions. But if your job requires complex operations you need to consider double-acting cylinders for better performance.

Advantages and Disadvantages of Single Acting Cylinder

• Advantages of Single Acting Cylinder : The most prominent advantage of using single acting cylinders is that it is easy to install, and these cylinders cost less and the maintenance cost is also minimum. The simple design of this cylinder makes the installation process easier and requires a small installation area. The cost of accessories like valve and hoses are also less in comparison to other types of cylinders. So, if you need simple tasks to perform it is better to install single acting hydraulic cylinders.

• Disadvantages of Single Acting Cylinder – Single acting cylinders cannot be used for complex operations. Compressed air that is used in single acting hydraulic cylinders require proper preparation and maintenance. The spring of the hydraulic system takes too much space that reduces working area of cylinder. With repeated use and after prolong service springs and pistons lose its consistency and requires replacement.

Difference Between single-acting hydraulic cylinders and double-acting hydraulic cylinders

The basic difference of single acting hydraulic cylinder and double acting hydraulic cylinder lies in the mechanism of operation of these two types of cylinders. In a single-acting cylinder hydraulic fluid acts only at one side of piston of cylinder. Pressure generated by the pump is transmitted through the fluid to extend the piton. In single acting hydraulic cylinder, the spring retracts to its original position by the force generated either by gravity or by the weight load. But in case of a double acting hydraulic cylinder, hydraulic fluid acts on both sides of piston. These cylinders have ports at both ends for retraction and extraction of piston and force is produced at both ends. In double acting hydraulic cylinders no external force is required for movement of piston to both sides.

The difference between a single acting hydraulic cylinder and double acting hydraulic cylinder that you can tell simply by looking at the cylinders is the number of ports these cylinders have. A single acting hydraulic cylinder typically has one port. This port is connected with the pump through the hydraulic hose fittings and the pressure is applied through this hose to extend the piston and the piston is then retracted to its original position by the weight. While in case of double acting hydraulic cylinders there are two ports attached to the cylinders. One port that is referred as the advance port is used to attach the hydraulic hose and extend the piston and the other port is used to retract the piston.

A single acting hydraulic cylinder is simple machine that is easy to assemble, install and maintain. On the other hand, the double acting hydraulic cylinders are complex machines that require more maintenance and comparatively difficult to install.

Functioning and maintenance of Double acting hydraulic cylinders are more complex than that of single acting hydraulic cylinders but they are good for completing repetitive jobs. Double acting hydraulic cylinders offer better precision in terms of application. So, if the job demands high precision and repetitive action double acting hydraulic cylinders are always better option to choose. Both the single acting and double acting hydraulic cylinders have their own advantages and disadvantages. It depends on the requirement of the job on the basis of which you need to select the type of cylinder.

Telescopic Hydraulic Cylinder is basically a linear actuator with stages of sleeves that extends and retract to do its job. Instead of a circular motion in Telescopic Hydraulic Cylinders the linear actuator moves in a straight motion. Each type of hydraulic cylinder has its own benefits and Telescopic Hydraulic Cylinder also has some benefits that makes it a preferred choice for specific industries and equipment.

Telescopic Hydraulic Cylinders provide longer stroke — The most predominant advantage of using Telescopic Hydraulic Cylinder is its longer stroke. Typically, collapsed length of a Telescopic Hydraulic Cylinder is only 20% to 40% of its fully extended length. This extra-long stroke that can be achieved from a Telescopic Cylinder that too with a compact package makes it unique from others and it is the biggest USP of this cylinder.

Multiple options with Telescopic Hydraulic Cylinder — Manufacturers produce Telescopic Hydraulic Cylinders in three basic configurations — single acting hydraulic cylinders, double acting cylinders and combination of both — single and double acting cylinders. The single acting Telescopic Hydraulic Cylinders produce thrust at one side for extraction and the retracted with the gravitational force. In double acting Telescopic Hydraulic Cylinder, thrust is produced at both ends and these cylinders extremely beneficial for precise extraction and retraction ratio. In case of combination of single and double acting Telescopic Hydraulic Cylinder you can get the benefits of double acting hydraulic cylinders with minimum complexities as it is with the single acting hydraulic cylinders. These varied options make Telescopic Hydraulic Cylinders a choice for many areas of operations.

Compact space saving installation — As it is already discussed that Telescopic Hydraulic Cylinder produce longer stroke than any other type of cylinders. That makes installation of Telescopic Hydraulic Cylinders very space saving. The compact design of these cylinders where the sleeves are inserted within each other during retraction require minimum space. This is the reason that Telescopic Hydraulic Cylinders are widely used in vehicles like dumping trucks and for precision jobs like mining where space is constraint however high capacity is the most important requirement. Even if you need low-capacity cylinders like agricultural equipment the compact design of Telescopic Hydraulic Cylinders make becomes an obvious choice for its compact design and easy installation.

Specific angular motion can be achieved — Telescopic Hydraulic Cylinders can provide operation of cylinder in a specific angle. Say if you want a lift to 60 to 90 degrees for different jobs. A Telescopic Hydraulic Cylinder can be used to achieve the exact elevation as per your requirement. This type of flexibility is hard to get from a cylinder with rod and shaft design.

It is true that Telescopic hydraulic cylinders are not meant for use in all types of applications. But in case of special circumstances, they are the only choice when it comes to selecting the right hydraulic system. Development in innovation of Telescopic Hydraulic Cylinders have expanded scope and advantages of these hydraulic systems manifolds. Compact design, longer reach with simple operations of Telescopic Hydraulic Cylinder makes it a popular choice for specific applications.
